A man whose body was found at the Baymont Inn, 1314 W. Lincoln Highway, died of natural causes in his sleep, said DeKalb County Coroner Dennis Miller.

The 59-year-old man was found by hotel staff about noon Monday in room 108 of the hotel. The hotel is less than a mile from campus.

“He was supposed to check out that morning,” said DeKalb police officer Angel Reyes. “When he didn’t, the hotel staff went to check on him.”

Miller said the man had a history of medical problems.

Reyes said the DeKalb Fire Department, the DeKalb Police Department and NIU Police Department responded to the scene.
